I have been backing up Exchange Server 2000 to travan using ntbackup (backing up the mailbox store not the files directly, i.e. the correct way). This has been running nightly as a scheduled task without problem. Circular logging is enabled on exchange.

Recently, every exchange backup fails. I have tried a manual ntbackup to a file on a separate hard disk and that also fails, so it's not a tape-thing. Also, even though circular logging is enabled, the old log files are not being replaced, so the disk is starting to fill (about 800MB of logs at the moment).

The ntbackup log is:

Given this plus the growing number of log files, it seems to me that the database may be in trouble.

What's wrong and how do I fix it!

Many thanks
